Screen flashes black.

I just got this my ASUS Q553U about 4 days ago. It occasionally flashes black for a split second. Usually every few minutes. I can't figure out what's going on! Can anyone help? Thank you in advance! Tabi

Sounds like insufficient power to the GPU. What power supply are you running? What motherboard do you have? Is your graphics card overclocked?
